Answer:
B(7 , -2)
Step-by-step explanation:
A(-9 , 6)
Midpoint = (-1 , 2 )
[tex]Midpoint = (\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}) = (-1 , 2)\\[/tex]
[tex](\frac{-9+x_{2}}{2},\frac{6+y_{2}}{2}) = (-1 , 2)\\[/tex]
Compare the x co ordinates and y co ordinates,
[tex]\frac{-9+x_{2}}{2}= - 1[/tex] & [tex]\frac{6+y_{2}}{2}=2[/tex]
-9 + x₂ = -1*2 & 6 + y₂ = 2*2
-9 + x₂ = -2 & 6 + y₂ = 4
x₂ = -2 +9 & y₂ = 4 - 6
x₂ = 7 & y₂ = -2
B(7 , -2)
8(x+2) when x=6 show how the answer is the answer them put = the answer thanks
Answer:
64
Step-by-step explanation:
Substitute 6 in for x in the equation to get 8(6 + 2). You need to follow the order of operations and solve what is in the parentheses first. 6 + 2 is 8, so that leaves you with 8(8). 8 x 8 is 64. 64 = the answer.

In a flash of sheer brilliance, Stefan invents a time machine! The machine uses a small nuclear reactor to generate the electricity it needs to travel back in time. There is a proportional relationship between how many years Stefan wants to travel back in time, x, and how much electricity (in megawatts) his time machine needs, y .
Answer:
[tex] y = x [/tex].
Step-by-step explanation:
Equation to represent the proportional relationship between years (x) and megawatts (y) is represented as [tex] y = kx [/tex].
Where k = constant of proportionality, which is y/x.
To find k, we can use the coordinates of any point on the line. Let's use (4, 4).
k = y/x = ⁴/4 = 1
Substitute k = 1 into [tex] y = kx [/tex].
✅Equation representing the relationship would be:
[tex] y = (1)x [/tex].
[tex] y = x [/tex].

Find the slope of the following graph 1) 0 2) No slope 3) 1
Answer:
it is 0
Step-by-step explanation:
hope it helps <3
Using the slope concept, it is found that this graph has a slope of 0.
Given two points (x,y) on a linear graph, the slope is given by the change in y divided by the change in x, that is:
[tex]m = \frac{\Delta_y}{\Delta_x}[/tex]
In this question, two of the points are: (1, 1.5) and (2, 1.5). Then, the slope is:
[tex]m = \frac{\Delta_y}{\Delta_x} = \frac{1.5 - 1.5}{2 - 1} = \frac{0}{1} = 0[/tex]
This graph has a slope of 0.

I need help with the equation inserted in the picture.
Answer:
x = 4
-4x+21 => 5
Step-by-step explanation:
The given triangle in the picture is isosceles triangle which means that two sides of the triangle are equal.
So,
[tex]Side\ 1: -4x+21\\Side\ 2: -4x+21\\Side\ 3: 6\\Perimeter = 16[/tex]
Now
Putting all the values in equation for perimeter
[tex]Side\ 1+Side\ 2+Side\ 3 = 16\\-4x+21 -4x+21 + 6 =16\\-8x +48 = 16\\-8x = 16-48\\-8x = -32\\\frac{-8x}{-8} = \frac{-32}{-8}\\x = 4[/tex]
Putting x = 4 in side 1
[tex]=-4(4)+21\\= -16+21\\=5[/tex]
Hence,
x = 4
-4x+21 => 5

Given: O ∈ AB , ON is ∠ bisector of ∠AOC, OF is ∠ bisector of ∠COB, m∠FOB=70°. Find: m∠AON
Answer:
AOC = 20 degrees
Step-by-step explanation:
We know that FOB is 70 degrees, and COF is 90 degrees. So just add 70+90 and get 160 degrees. Then you subtract that from AOB which is 20 degrees.

B. 50°
C. 80°
D. 90°
Answer:
d
Step-by-step explanation:
Answer:
D. 90
Step-by-step explanation:
So you're given 130 degrees. that 130 angle and the angle inside the triangle next to it, are supplementary which means they add up to 180. So you have a 40 degree and a 50 degree angle + x. together they must add up to 180
40+50+x=180
90+x=180
x=90
Point R on the coordinate grid below shows the location of a car in a parking lot. A second car needs to park 6 units above R to leave room for a utility truck. What are the coordinates of the location of the second
Answer:
[tex]R' = (-4 , 4)[/tex]
Step-by-step explanation:
Given
See attachment for the grid coordinate
From the attachment, we have that:
[tex]R = (-4,-2)[/tex]
Required
Determine the coordinates of the second truck
Represent the position with R'
From the question, we understand the position of R' is 6 above R
When a point (a,b) is moved n point above, the new point becomes (a, b + n)
So:
[tex]R = (-4,-2)[/tex]
When moved 6 points above becomes:
[tex]R' = (-4 , -2 + 6)[/tex]
[tex]R' = (-4 , 4)[/tex]
Hence, (-4,4) answers the question

The following table shows the salary of 7 people in an office last year.
Name Income

Frankie £27500
Grace £15000
a) Work out the mean income to 2 DP.
b) Deva was given a large bonus for 30 years service.
Excluding Deva's income, what was the mean income for the remaining 6 workers to 2 DP?
Answer:
a. Mean = £27928.57
b. Mean without Deva's income = £19416.67
Step-by-step explanation:
The mean is calculated by dividing the sum of values by number of values. Given 7 values will be used to calculate mean.
So,
Number of values = n = 7
Now,
[tex]Mean = \frac{Sum}{No.\ of\ values}\\=\frac{13500+27500+13750+79000+19250+27500+15000}{7}\\=\frac{195500}{7}\\=27928.5714..[/tex]
Rounding off to two decimal places
Mean income = £27928.57
Now we have to calculate mean without Deva's income so the number of values will be 6 and the sum will be:
[tex]Sum = 195500-79000 = 116500[/tex]
The mean without Deva's income is:
[tex]Mean = \frac{116500}{6} = 19416.6666..[/tex]
Rounding off to 2 DP
Mean = £19416.67
Hence,
a. Mean = £27928.57
b. Mean without Deva's income = £19416.67

The brown family has 5 liters of lemonade. Each liters of lemonade weighs 1 kilogram. At the end of the day they have 290 grams of lemonade left. How many grams of lemonade did they drink.
Answer:
4710grams of lemonade.Step-by-step explanation:
Step one:
given data
the brown family has 5 liters of lemonade that weighs 1 kg per liter
this implies that they have 5kg of lemonade.
convert 5kg to grams we have 5*1000= 5000grams
(because 1000g is equal to 1kg)
Step two:
if at the end of the day there was 290grams left, then they drank
=5000-290
=4710
They drank 4710grams of lemonade.

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 18 fl oz per . How fast was the pipe leaking in gallons per ?
Answer:
0.140625 gallons per
Step-by-step explanation:
By doing a quick search we discover that there are 1 fl oz is equal to 0.0078125 gallons. Therefore, in order to find out how fast the pipe was leaking in gallons, we simply multiply the rate of fl oz by the number of gallons for every fl oz like so...
18 fl oz * 0.0078125 gallons = 0.140625 gallons
